No problem, always choose a method you're most comfortable and confident with.

We shall await for developments to unfold.

sorry if i'm writing a lot one thing I did not understand. 120 grams refers only to the article or does it include amazon box and article box?

120 grams refers only to the article or does it include amazon box and article box?

In this case, you're SEing the CPU alone, so the weight relates to that.

If (for example) an Item and Its box Is under the 120 gram bracket, you can SE the lot - Item & box.
